GeneralThe longitudinal deck length is defined by the support lines selected in this section, while the transverse direction deck properties are determined by the cross-section defined in the previous stage. Cross-Sections: | Info |

To generate a deck, at least two row definitions must be made. The required definitions are the support line and its cross-section at the start station, as well as the support line and its cross-section at the end station. However, the Offset from Support Line parameter should not be used for either of these definitions, as it is not the correct parameter for extending the deck before the start station or after the end station. Instead, the Initial Cantilever Length and End Cantilever Length parameters of the Concrete Deck object should be used. |
Offset From Support Line: If the entered cross-section is intended to vary between the start and end stations, this parameter can be used to assign different cross-sections to the relevant corresponding locations. Cross Section: Select the cross-section defined prior to this step. Skew Angle: A positive skew value rotates the start and end location in a clockwise direction, while a negative skew value rotates the cross-section counterclockwise. Selecting a skew value for any interior support line (pier) will impact the finite element generation logic at that location. Variation w/Next Segment[None/Linear/Parabola]: For visual representation, refer to the figures below.
 
Girders: To create the 3D geometry for the haunch and finite element mesh of the deck, input for the girder is required. To ensure accurate extraction of composite forces, the library component will generate a minimum of two shell elements between two girders. Taper: In the overhang regions, users can choose whether or not to include taper by selecting "yes" or "no," as shown in the figure below. This input will impact the haunch load computation.  |
